Gynandromorphy in Eulaema atleticana Nemésio (Apidae, Euglossini)
A gynandromorph specimen of Eulaema atleticana Nemésio, the first registered in Eulaema, is described. The E. atleticana gynandromorph was captured using an eucalyptol scent trap, in the Mata do Buraquinho Reserve, an Atlantic Forest fragment.

Floral Integration and Phenotypic Selection on Floral Traits of <i>Ipomoea cavalcantei</i> (Convolvulaceae), a Rare, Endemic, and Endangered Species to the Amazon Ironstone Outcrops. [PDF]
This paper analyzed the evolutionary potential of Ipomoea cavalcantei (an endemic species from the Amazon) by using floral integration and phenotypic selection analysis. The analyzed population presented floral integration in style length, probably due to selective pressures from pollinators on floral traits related to pollen deposition.

Mountain colonization precedes shifts away from bee pollination in Melastomataceae. [PDF]
Summary Shifts among different groups of pollinators are central in the evolution of flowering plants, yet mechanisms underlying pollinator shifts remain unclear. Environment‐induced reduction in pollinator availability and hence efficiency may destabilize ancestral plant–pollinator interactions and trigger shifts to new, more efficient pollinators ...

Plants, Pollinators and Pheromones: Promises and Lies of Semiochemicals. [PDF]
ABSTRACT Pollination is traditionally regarded as a quintessential mutualism, yet many plants employ deceptive strategies to achieve reproductive success. Among the most intriguing is sexual deception, wherein flowers mimic the sex pheromones and visual signals of female insects to attract male pollinators—without providing any reward.
